Jack Osbourne has revealed that being diagnosed with multiple sclerosis was "the scariest moment" of his life.

The Dancing With The Stars contestant was told he had the condition last year, not long after he married his wife Lisa and just weeks after their daughter Pearl was born.

"I think the scariest moment in my life was when I was diagnosed with multiple sclerosis," said Jack. "I lost the vision in my right eye, and came to find out that the numbness in my legs from 18 months earlier was a result of the same thing.

"It was a real shock for my family when I had to break the news to them. None of us saw this coming. MS is unpredictable, which means I never know how or when it's going to affect me. Whether [I have] problems with my vision… numbness, fatigue – that's just something my family and I now have to think about every day.

"I now know that life doesn’t end when you’re diagnosed with MS. I'd just become a father so I was determined to not be beaten by it. But learning to adapt can be a real challenge."

Jack made the revelation as part of a televised appeal for the MS Society, which will be broadcast on 17 November on BBC One at 5:05pm.
